Tomorrow's exam

[mrmvp]

Hello

I have a question regarding the usage of apostrophe in the following example

1- "Tomorrow's exam" and "student's name" ,why not tomorrow exam? If you please help differentiate between the apostrophe when it shows possessiveness and when not

Is the apostrophe in "tomorrow's exam" shows possessiveness ? My understanding of the apostrophe is that it shows possessiveness, such as "Adam's pen" and "the boys' pens".

Hello.
I have a question regarding the usage of apostrophes in the following example.

Pay attention to your punctuation.

1- "Tomorrow's exam" and "student's name". Why not "tomorrow exam"?

In English, you must use the possessive for such phrases. The exam belongs to "tomorrow" (is identified by "tomorrow").

If Could you please help me differentiate between the possessive apostrophe when it shows possessiveness and other apostrophes? when not

Take a look at the information and try doing the exercise in the following link. Post below if you still need help.

Is Does the apostrophe in "tomorrow's exam" show possessiveness?

For example:
Tomorrow's exam has been postponed. [possessiveness]
Tomorrow's exam day. = Tomorrow is exam day [not possessiveness]

My understanding of the apostrophe is that it shows possessiveness, such as "Adam's pen" and "the boys' pens".

See above.
